Pradimicin S was isolated from the culture filtrate of Actinomadura spinosa AA0851. NMR and MS analyses proved that pradimicin S is the 3'-O-(3''-O-sulfo-beta-D-glucopyranosyl) analog of pradimicin A, a new member of the pradimicin family of antibiotics. Stereochemical assignment was made by correlating pradimicin S with pradimicin L.

eight salvia l. species including s. spinosa l., s. reuterana boiss., s. macrosiphon boiss., s. syriaca l., s. nemorosa l., s. virgata jacq., s. sharifii rech. f. & esfand. and s. mirzayanii rech. f. & esfand. were studied for flavonoid compounds. these constituents were analyzed using two-dimensional maps on silica gel 60f thin layer chromatography. the flavonoid compounds of each spec...

Salvia columbariae extracts were examined for the presence of salvianolic acids by HPLC-MS and NMR. A new salvianolic acid, β-sitosterol lithospermic acid, was found.

The known flavone, chrysin (1) and the known flavone glycoside, chrysin-7-O-(β-D-glucopyranoside) (2) together with vomifoliol, loliode and cinnamic acid have been isolated for the first time from the leaves and flowers of Calycotome spinosa (L.). Lamk, theirs structures were established on the basis of spectroscopic technical; H-, C-NMR, 2D NMR and MS (I.E).

BACKGROUND Pycnocycla spinosa (P. spinosa) a member of the Umbelliferae family is traditionally used for treatment of different ailments. OBJECTIVES This study aimed to evaluate the total phenolic and flavonoid content of P. spinosa extracts (methanol, ethanol and aqueous) and their antioxidant and antimicrobial effects. MATERIALS AND METHODS The antimicrobial activity of different extracts...

Salvia leriifolia (Lamiaceae) is an endemic endangered plant of Khorasan and Semnan province from Iran. Poor germination of seeds for this plant is a serious problem tomass production. The first step to improve this precious plant is to produce sterile plantlets in order to prepare explants of appropriate vigor. In this study, in vitro culture of Salvia leriifolia embryo was performed through a...

Eight Salvia L. species including S. spinosa L., S. reuterana Boiss., S. macrosiphon Boiss., S. syriaca L., S. nemorosa L., S. virgata Jacq., S. sharifii Rech. f. & Esfand. and S. mirzayanii Rech. f. & Esfand. were studied for flavonoid compounds. These constituents were analyzed using two-dimensional maps on silica gel 60F thin layer chromatography. The flavonoid compounds of each species were...

Over the past decades, there has been increasing attention on polyphenol-rich foods including fruits and vegetables on human health. Polyphenols have been shown to possess some potential beneficial effects on human health and they are widely found in foods consumed by populations worldwide. Capparis spinosa (C. spinosa) is an important source of different secondary metabolites of interest to hu...
